FOLDING UMBRELLA,

Application filed March 1, 1912. Serial No.A 684,102.

To all whom e' may concern: y

Be it known that I, Biron AnoLrH NYGREN, a citizen of the United States residing at Minneapolis, in the county of Hennepin and State of Minnesota, have invented certain new and useful `Improvements in Folding -Uinbrellas; and l do hereby declare thev folend,it consists of the novel devices and combinations of devices, hereinafter de-V scribed and dened in the claims.

The invention is illustrated in the accompanying drawings wherein like characters indicate like parts throughout the several views. i,

Referring to the drawings, Figure l is a view partly in side elevation and partly in section showing the improved umbrella in an open position, some parts being broken away and other parts removed; Fig. 2 is a view principally in longitudinal section taken centrally through the improved unibrella showing the saine in a partly folded position; Fig. 3 is a detail View in section showing one of the locksfor the cane sections; Fig. l is a view in longitudinal section, taken on the line ai* x4 of Figxpl; Fig. 5 is a transverse section taken on the line m5 :c5 of Fig. el; Fig. 6 is a transverse section taken on the line ze `fr@ of Fig. 3; and Fig. Z is a detailed view showing one of the hinge `connections between the outer and interin crosssection. The cane section 1, at its lower end, is provided with a hand piece 5. A spring latch 6 isrigidly secured within the cane section 1 near its inner end, and is provided with a cam head that Works within and is guided by a, slot formed `in` said cane section. Formed in and near the 'outer end of' the cane section 2Y in a lock slot 8, arranged to register with and receive the n cam head I ol' the latch 6 to loch the cane section 1 to the cane section 2 in its extended Specification of Letters Patent.

position, and againstendwise movement in either direction. Rigidly secured to the cane section 3 is a spring latch 9 having a` cani head 1.() that works within and is guided by a lock slot formed in said4 cane section near its lower end. Near the inner end of the cane section 2 is formed a slot 11, arranged to register with and receive the cam head 10 to lock the cane section 2 to the cane section 3 in its extended position, and against end' The cam.

wise movement in either direction. heads 'Y and 10 and the lock slots 8 and 11 are all vertically alined.

An annular cap 12 having depending peripheral hinge .lugs 13 is detachably and rigidly secured to the outer end of the cane section 3 by means of a screw bolt-14. Folding cover supporting ribs are pivotallyconnected near their inner ends to the hinge lugs 13. As best shown in Figs. 1 and 2, these cover supporting ribs are each niade up of an inner section 15, an intermediate section 16, and an outer section 17. The inner and intermediate sections 15 and 16 are connected by hinged joints 18, arranged to permit the rib sections 16 to be folded inward onto the rib sections 15, as best shown in Fig. 2. Hinged joints 19 connect the intermediate and outer rib sections 1.6 and 17 and are arranged to permit the rib sections 17 to be folded outward onto the inter-` A cover 21, of any suitable material, is-

stretched over the cap 12 and supporting ribs. rlhis cover -21 is secured to the cap 12 by means of a washer 22 on the screw "bolt lll, and its periphery is secured to the free ends 015 the rib sections 17 by stitching or otherwise. The drawing action of the cover 21 tends to hold the free ends of the rib sections 17 pulled downward.

riphery is integrally formed on the inner end of 'the cane section Folding stay rods 2l, at their lower ends, are sealed in the notches of the flange 23 and pivotally'se- 4cured thereto by ineainf et a wire lia-iid 23 seated in the gro-ove of said flange. it their ,outer ends, the stay rods 24: are pivotally at ,tached to the intermediate poi-tiens or' the An annular l llano'e 23 havinO a notched and rooved e iio rib sections 16. The stay rods 24C are each made up of two sections connected by a hinge joint 26, arranged to permit the stay rods to fold inward, as best shown in Fig. 2.

Slidably mounted on the cane section 3 is a collar 27 having a notched and-grooved periphery. Links 28 have their inner ends lseated in the notches of the collar 27, and are pivotally attached thereto by means of a wire band-29 seated in the groove of the collar.. The outer ends of the links 28 are pivotally attached to the intermediate poi14 tions of the inner sections of the stay rods 24. A head block 3() is slidably mounted on the cane section 2. Slidably mounted in perforations in the flange 23 is a pair 'of rods 81 rigidly secured at their upper ends to the sliding collar 27, and rigidly secured at their lower ends to the head bloei: 30. A spring pressed latch 32 is pivotally mounted on the head block 30 and is adapted to engage' thc flange 23 to hold the head block 30 interlocked with the cam section 2 lwhen the i umbrella is folded.

Stop flange 33 is spaced below the cap 12 and rigidly secured to the cane section 3. Slidably mounted on the cane section 3 between the cap 12 and the stop flange 33, is a sleeve 34.- terminating at its lower end in an outwardly extended flange 35, having a notched and grooved periphery, similar to the flange 23 and collar 27. The inner ends of the rib sections 15, beyond their pivotal connections are curved inward and downward and are provided with segmental slots 36. The slotted ends of the rib sections 15 are mounted in the notches of the flange 85 and are loosely secured thereto by means of a wire band 37, mounted in the groove of said flange. rhese slotted ends of the rib sections 15 are adapted to engage the stop flange and limit the opening movements of the rib sections 15. Surrounding the sleeve fill is a coiled spring 38 compressed r between vthe cap 12 and the flange 3o, tending to hold the rib sections in engagement with said stop flange 33. A transversely extended pin 39 is rigidly secured to the sleeve 34; and works vertically in a pair of' diametrically opposite slots l0 formed in the cane section 3.

'lhe operation of the improved umbrella may be briefi y stated as follows :-Normally, the spring latches 6 and 9 hold the sections olf the cane in their extended or operative positions, and the stay rods 2li and spring 38 hold the cover supporting ribs in their open positions.

'lo close or hold the improved umbrella, the head block 30 is first moved inward into enga/gement with the flange 23, and is locked thereto by means of the latch 32. This moveinent of the head block 5l() through the several connections to the stay rods 24, first buckles said stay rods, then the rib sections 16 are folded inward onto the rib sections 15, and, at the same time, all, of the rib sections are partly folded, as shown in'Fig.-

2. During the first process of positively folding the rib sections 15 and 16, the rib sect-ions 17 are folded under the action of' gravity toward the. rib sections 16, also shown in Fig. 2.

After the head block 30 has been locked to the flange 23, the cam head 7 is pressed inward by the thumb and, at the same time, the cane section l is forced inward, thereby -camming the head 7 out of the slot 8. Continuing the movement of the cane section 1, the inner end thereof engages thecam head 9 and forces the same outward into a position to be engaged by the inward movement of the, cane section 2 and, thereby, forced cbmpletely out of the slot 11. The cane sections l and 2 are of substantially the same length and the continued inward movement of the cane sectio-n 1 carries therewith, by.

means of the hand piece 5, the cane section 2.

Duringl the final inward movements of the cane sections 1 and 2, the cross pin 39 is engaged thereby and the connected sleeve 34- moved against the tension of the spring 38. This final movement of the cane sections l and 2 completes the folding move- 2. An umbrella comprising a cane, a cap,

and a stop flange spaced apart and secured to said cane, cover supporting ribs pivotally connected to said cap, a sleeve slidably mounted on said cane between said cap and stop flange and connected to said ribs inward of their pivotal connections, and a spring compressed between said cap and sleeve, tending to hold said ribs extended and in engagement with said stop flange.

3. In a folding umbrella, the combination with a sectional cane, of cover support-innribs made up of inner, intermediate and outer sections pivotaliy connected, said inner sections being pivotally connected to said cane, said intermediate sections arranged to be folded outward onto said inner sections, said outer sections arranged to be 'j folded inward onto said intermediate sections, folding stay rods pivotally connecting said intermediate 'rib sections and said cane, extensions on said outer sections for holding the same below dead centers, and a cover otnlly connected to said cane, a sliding sleevel messes stretched over said ribs tending to pull the free ends of said outer ribs downward.
